Managing the water distribution network with a Smart Water Grid

In Singapore, the implementation of a Smart Water Grid system supports the Public Utilities Board (PUB)’s mission to supply good water 24/7 to its customers. With sensors and analytic tools deployed island-wide to provide a real-time monitoring and decision support system, the Smart Water Grid system enables PUB to manage the water supply network efficiently, ensuring that all Singaporeans will continue to enjoy a reliable and sustainable water supply for generations to come. This paper covers the five key aspects of the Smart Water Grid system, in relation to both the key operational aspects of a water distribution system (asset management, leak management, water quality monitoring) and the customers’ end (automated meter reading and water conservation). For each aspect, the paper focuses on the challenges, current technology, PUB’s experience with technology and identified gaps, and the technology roadmap.
